Eaton LPN-RK-6SP Fuse - Class RK1 Time-Delay, CE Marked
Part Number: LPN-RK-6SP
Quick Summary
The Eaton LPN-RK-6SP fuse provides time-delay protection for industrial control circuits. Engineers often face nuisance trips and downtime when protective devices react too aggressively to startup surges or transient faults. This CE-marked Class RK1 design pairs a dual-element, current-limiting fuse with a time-delay characteristic to balance protection and continuity. The integration of a reliable interrupt rating—up to 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc—helps ensure safe fault handling in demanding environments. For panel builders and automation engineers, this fuse offers predictable protection, compact form factor, and straightforward installation, reducing total cost of ownership while supporting European compliance and robust electrical protection in control panels.

FAQs
The LPN-RK-6SP uses ferrule-end terminations and a compact 2 in length, making it compatible with standard Bussmann-style fuse holders found in many control panels. Its dual-element, time-delay design reduces nuisance trips during motor startup while maintaining robust protection for circuits up to 6 A.
Key specs include 6 A amperage rating, voltage rating of 250 Vac / 125 Vdc, interrupt ratings of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc, and a time-delay response characterized by protection within 8 seconds at 500% overload. The fuse is non-indicating and Class RK1 compliant with dual elements for enhanced protection.
Yes. The time-delay, dual-element design accommodates motor startup surges, while the current-limiting feature helps limit fault currents to downstream devices. Its compact form factor and ferrule-end connections streamline installation in motor control centers and automation panels.
The LPN-RK-6SP is CE Marked, indicating European compliance. It aligns with Class RK1 fuse construction standards, offering reliable protection for control circuits while supporting compliance workflows in European facilities.
By minimizing nuisance trips and controlling fault currents, the LPN-RK-6SP reduces unplanned downtime and equipment damage. Its modular ferrule-end design simplifies field replacements, reducing labor time and inventory complexity in maintenance programs.
